The Modified Mercalli intensity scale ( MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth.There are two main scales used in the seismometers: (1) the Mercalli Scale and the Richter Scale. Mercalli Scale. The scale represents the intensity of the earthquake by analyzing the after-effects like how many people felt it, how much destruction occurred etc. The range of intensity is from 1-12.The moment magnitude scale is often referred to by the name of its predecessor, the Richter Scale. Measurements on the Modified Mercalli Intensity (MMI) scale range from I to XII and are based solely on damage assessment and eyewitness accounts. Intensity measurements near the source of an earthquake are generally higher than those at a distance.A modified Mercalli intensity scale is used to quantify the earthquake's effects.That's why you can't directly convert the Richter or Magnitude scale to the Mercalli scale — although the released energy, local geology, terrain, depth of an earthquake and distance from the epicenter are all still the same. Thus, the Mercalli scale describes how …
The Modified Mercalli Intensity Scale provides scientists with a method to quantify the shaking generated by an earthquake, as experienced at any point at the earth’s surface.

The intensity scale is named after Mercalli, an Italian seismologist. The intensity scale takes into account the visible damage caused by the event. The range of intensity scale is from 1-12.Intensity scales, like the Modified Mercalli Scale and the Rossi-Forel scale, measure the amount of shaking at a particular location. An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are.The MM scale measures intensity of shaking, at any particular location, on the surface. It was developed from Giuseppe Mercalli 's Mercalli intensity scale of 1902. While shaking experienced at the surface is caused by the seismic energy released by an earthquake, earthquakes differ in how much of their energy is radiated as seismic waves. Moreover, Giuseppe Mercalli compiled a 6° intensity scale; to identify and categorize high-intensity seismic damage more accurately and meticulously, the seismic intensity was reclassified in reference to the R–F scale. This 6° standard was later extended to a 10° standard and translated in 1902.Jun 11, 2023 · Key Takeaways. Richter Scale measures the magnitude of an earthquake, while Mercalli Scale measures the intensity of an earthquake at a specific location. Richter Scale is calculated based on the seismic waves generated by an earthquake, while the effects of an earthquake on people, structures, and the environment determine Mercalli Scale. Two of the most common methods used to measure earthquakes are the Richter scale and the moment magnitude scale. The Mercalli scale also measures the effects of an earthquake at different locations.The Modified Mercalli intensity scale (MM, MMI, or MCS), developed from Giuseppe Mercalli’s Mercalli intensity scale of 1902, is a seismic intensity scale used for measuring the intensity of shaking produced by an earthquake.The Mercalli intensity scale was originally revised from the simple ten-degree Rossi-Forel scale by Italian volcanologist, Giuseppe Mercalli in 1884 and 1906.
